Hepsia Advanced Features
The Advanced tab grants you swift access to a set of advanced features, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and apps without the need to log out of the web hosting Control Panel. Depending on the web hosting package, these tools are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish
Varnish Cache is a web application accelerator also referred to as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will increase your site's speed. One of the essential merits of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to determine how incoming requests should be tackled.
Memcached
Memcached is a generic distributed memory object caching system for boosting the load speed of dynamic database-driven sites. It is used to lower the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached distributed memory caching system uses a client'server architecture. The Memcached memory object caching system is used by some of the most traffic-heavy web sites on the World Wide Web and is supported by popular Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a software system for building scalable Internet apps. Written in JavaScript, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and effective, ideal for real-time content-heavy network applications. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source RDBMS. A database engine is the main software component that a database management system uses to create, read, modify and delete data from a database. Its latest release offers significant improvements in efficacy, security and usability. InnoDB provides the standard ACID transaction features, as well as foreign key support. It is included by default in most binaries distributed by MySQL AB.
